Signal strength is given in dBm and should be somewhere between -90 and -25. (Notice the negative!) Smaller is stronger, but stronger than (or "lower than") -30, or preferably -40 is not recommended.

hi hlekat, the best bet here is 900Mhz if you want a link that can make you sleep with all your eyes closed. However, consider increase in height and high gain antenna as wirelessrudy suggested. Changing to high powered radio wont improve your signal. i hope this will save your time. Regards Abiola...

Of my 250 full MT units (rb + radio) and all running v5.4 with updated firmware and all in simple routing with src-natting on the CPE to separate client LAN form wlan network, I still have roughly 8% of units that have the ethernet ports disabling and enabling. It happens on almost all type of rb's ...

Re: Noise Floor Dropping

If you set the noise floor manually, it will not dynamically calibrate it, and prevent you from having the noise floor drop low. You may want to really investigate the root cause of the problem, and perhaps not just treat the symptoms. Do you have other equipment near your main antenna site? have y...

Re: RouterOS 5.5 Released

Nothing about any wireless improvements (NV2 disconnects etc.)! And nothing about `port flapping` I guess? (It still exists on 5 different rb's I have, all with 5.4 and updated firmware and MT radio cards) To me this looks a ´minor´ upgrade I might as well consider not to use... :( And why do I only...

Re: Ghost disconnects

Like Egate says, ubnt is not the solution. Even if their stuff might work easier in ´plug and play´ modus. Frst of all, their hardware is not as reliable as routerboards. The failure rate is much higher. Second, it has only some 60% of the options as a fully squeezable ROS like MT has to offer. Thir...

In environments where different bandwidths are in use finding a free channel and troubleshooting radio issues is a bit complicated now. Each bandwidth needs its own scan and that info needs ...

remote wireless scan?

Is there anyway to execute a wireless scan on a remote unit in v5.4? Normally when you issue the command the connection gets lost. Maybe in safe mode the unit comes back after a while, but then I have no more result of the scan... This feature would be very much needed in ever increasing spectrum no...
